The purpose of our study was to analyze the effects of mission complexity on pilot mental workload, situational awareness, and pilot performance and to develop models by means of structural equation modeling. Earlier studies indicate that mission complexity affects mental workload and that mental workload affects situational awareness, which, in turn, affects pilot performance. In the first phase of this study, 20 fighter pilots performed 150 missions. In the second phase, 15 pilots performed 40 simulated missions. The pilots answered questionnaires on mission complexity, mental workload, mental capacity, situational awareness, and performance. During the simulated missions we measured eye fixation rate, heart rate, and blink rate. Model analyses show that mission complexity affects workload and that workload affects situational awareness and performance. Significant relationships occur between heart rate and rated workload, mental capacity, situational awareness, and performance. Model analyses show a workload factor combining psychological and physiological aspects and a performance factor combining situational awareness and pilot performance. Significant relationships occur among heart rate, eye fixation rate, and blink rate.
